An “image dissector tube” from the Farnsworth Pickup Camera, 1936. Via archive.org.
More early 9px camera results, this time “real” data (ie: not random analog fluctuations but actual sensor readings) through an old 35mm SLR lens.
Some early tests for an experimental digital camera: light sensors > Arduino > saved as BMP files on an SD card/displayed in real-time on an array of LEDs.
With a new, sandblasted piece of plexi (instead of hand-sanded), more images from what I am now calling the Webcam View Camera (35mm lens projecting onto a piece of ground plexi, picked up by a cheap webcam, captured by screen-grab).
